- Application filed June 11,1896. Serial No. 595,184. (No model.)Patented in England June 13,1896, No. 13,115; in France June 20,1896,11'0. 244,818, and in Canada February 1Z,1897,No-54,976.

To all whom it may concern:

Be it known that we, CHARLES PHILIPPE GHO UETTE and ANTOINE Mo'IsEMORIN, citizens of the Dominion of Canada, residing at the town of St.Hyacinthe, in the county of 'St. Hyacinthe and Province of Quebec,Oangenerator-that is, one in which the production of the gas isautomatically regulated; and it consists in the novel construction andcombination of the parts hereinafter fully dean outer tank A, having abottom a, but no top, and into which is placed another tank or holder B,having no bottom, but whose top is formed by means of a separate chamber0, whose bottom portion 0 is funnel-shaped and is provided with acircular opening at 0 just large enough to smoothly slide along the rodD. This vessel or chamber 0 is also provided with the guide 0 or anyother suitable substitute,

so that when the tank B rises it always occupies the same position inthe tank A.

Now to put the apparatus in operation water is poured into the bottom ofthe tank A, by means of the tubea or otherwise, until the required levelis reached, which can be seen by a suitable water-gage a However,

in doing this the air contained in the vessel B is compressed, so thatby opening a valve placed on the outlet-pipe 0 (not shown on thedrawing) this air escapes by passing through the pipe 0 which isprovided with a checkvalve, (not shown on the drawing,) so as to allowno vapor of water to get into the chamber O. This being done and acertain amount of pulverized or granulated carbid of calcium being putinto the funnel 0', when held up by means of the rings K or otherwise,through the opening E, which is closed by a suitable stopper, theoperation at once begins on unhooking the rings K, for then a certainamount falls down through the opening 0 which, when the tank B is down,as shown on the drawing, is opposite the conical end (1 of the rod D andis consequently open. However, as the production of gas takes place thepressure in the tank B runs up, and when the production is more than thedemand the pressure runs up enough to force the water up between thetanks A and B, as shown, and at a given moment raises the tank B.However, when this happens the opening 0 comes opposite the cylindricalportion of the rod or stopper D, and no more carbid of calcium issupplied, thus stopping all production of gas, for as the chemical isput into the water when in a highly subdivided state its decompositionis almost instantaneous on reaching the water, so that the stopping ofthe supply stops the production of the acetylene. As the gas passes outthrough the pipe 0 into the chamber 0, and from thence to the point ofconsumption through the pipe C, it comes into contact with thepulverized carbid of calcium F and is thus completely dried of all itsentrained water, as the cal-bid of calcium is highly hygrometric. Whenthe pressure runs down, the tank B falls, and again the carbid ofcalcium pours down through the opening 0 as it comes opposite the cone(1, and a new quantity of gas is made, the operation continuing asbefore The rod or stopper D is held in position by any suitable means;but it is joined to the bottom of the tank A by means of a small rod d,passing through the bottom a, where it is provided with a thumb-screw dso as to regulate the height of the rod or stopper D. This small rod clis also provided with a shoulder ical is not mixed up with the residueof the decomposition and the water.

The top of the apparatus is made heavy enough to maintain a suitablepressure in the holder B when the provision of the pulverized orgranulated carbid of calcium is about run out.

Having described our invention, .what we claim, and desire to secure byLetters Patent, 1s-

In an acetylene-gas generator, the combination, of an outer tank tocontain water in the bottom, means for introducing this water, a smallrod (1 surmounted by a larger rod or stopper D having its point ofjunction with the rod (1 conical in shape, means for regulating thelength of the whole, and secured to its bottom, and means for regulatingthe amount of rise of the inner tank with an inward tank or holderhaving its top formed by means of a tank or chamber to contain thepulverized or granulated carbid of calcium, and having a funnel-shapedbottom provided with an opening at its lower extremity, of justsuliicient size to freely slide over the rod or stopper D, means ofintroducing the carbid of calcium into the funnel-shaped chamber, meansfor the escape of the gas to the point of consumption, and means toguide the inward tank or holder into the outward tank, substantially asdescribed, and for the purposes set forth. v

In testimony whereof we have affixed our signatures in presence of twowitnesses.
